PERFORATING-MACHINE.

. To all whom it may concern.

seHLAeER, a citizen of the United States, re-

siding at Cincinnati, in the county of Hamilton and State of Ohio, haveinvented certain new and useful Improvements in Perforatinglachines, ofwhich the following is a specification. r V

My invention relates to perforating machines adapted for providing theparts of shoe uppers, harness, saddlery goods and the like, withperforations, and the invention relates particularly to novel means andhandling the material is enhanced.

It is the object of my invention to provide novel means whereby closedmargins may be readily so placed with relation to the punch and the gageas to locate the gage within the closed margin, and further to providenovel means whereby the material having the closed margin may be laidsubstantially fiat upon the material-support and guided in substantiallyflat relation around the gage and under the punch.

It is the object of my invention, further, to provide a perforatingmachine with a shiftable gage for the material, past which the materialof the closed margin may be slipped, for placing the closed margin to beperforated about the gage, the closed margin being then guidedcontinuously throughout its closed path against the gage and lengthwisepast the reciprocating punch, and further to'pro'vide the perforatingmachine with a gage and a hold-down finger for. the margin of thematerial and means for shifting the gage relative to the holddown fingerfor-passageof the material past the gage in a direction reverse to thedirection in which the edge thereof is presented to the gage during thepunching operation. It is the object of my invention, further, toprovide a perforating machine with a hold-down'finger and a resilientlyyieldable gage. for the materialadjacent to the holddown finger, soarranged that the gage will yield with relation to the hold-down fingerby pressure thereon of the material while moving the material past thegage into range with the punch.

The invention will be further readily understood from the followingdescription and claims, and from the drawings, in which lat ter Figure 1represents a side elevation of so Specification of Letters Patent.

Fig. 7 is a similar view of the parts,showing the edge of the margin to be punched against the gage under theholddown finger. Fig. 8 is a front elevation of the gage. Fig. 9 is adetail of the same shown in front elevation. Fig. 10 is a horizontalsection of the same taken on the line 10-10 of Fig. 7. Fig. 11 is avertical sectional detail of the same on the'line 11-11 of Fig. Fig. 12is a detail of the same in horizontal section on the line 12-12 of Fig.5. Fig. 13 is a bottom view of the table showing the means for guidingthe cushionstrip; and Fig. 14 is avertical section of the same taken onthe line 14-14 of Fig. 13. I have exemplified my improvement as appliedin, a perforating machine such as shown and described in Letters PatentNo. 843,899, issued tome February 12, 1907, for improvements in punchingmachines.

There is a frame 11, which has an arm 12 projecting therefrom, in whichthere are bearings 13having rods14 secured therein. A punch-ram head 15has bearings 16 slidable on the rods 14, suitable means being provided,for instance' as shown and described in said aforesaid patent forlaterporting table22 supported on the frame, the

parts having a material-supporting surface 23 for the'material 24represented as a closed vamp.

' A. presser-foot 25 is secured to a rod 26 slidable in bearings 27,wherein the rod is prevented from turning. The presser-foot is arrangedto be reciprocated up and down in consonance with the retractingmovements of the punch, instanced as a feeding punch, so as to hold thematerial in place while the punchis retracted to initial posi- I 26,whereby, upon rccking of the rock-shaft 31 by means of the treadle, therod 26 and the presser-foct 25 are raised off the material. The partshereinbefore mentioned mayall be constructed, mounted and operated inmanner described in my aforesaid patent.

If desired, a cushion-strip 38, which may be a strip of paper, asexplained in said patent. may be interposed between the cut iting edgesof the punch and the anvil.

,jln operation in the present exemplification of my inventicn, the punchdescends into the material. firmly against or into the cushion-strip,then slightly rises, moves in the feeding movement of the punch forfeeding the material above and with relation to the cushion-strip, thenslightly descends, and then rises out of the material and retracts toinitial position. as shown and described in my aforesaid patent. Aslight feeding movement may be imparted, tothe cushion-strip, which maybe accomplished by means of a feed-wheel 39 coacting with an impact-face40, the feed-wheel being intermittently operated as shown and describedin my aforesaid patent.

The cushion-strip is arranged to be received offa suitable supply-rollacross a ledge 41 on an adjustable guide-plate 42 having guide-lugs 43thereon contacting the edges of the strip for guiding its path. ittension-bar 44 is arranged to press upon thecushion-strip for retardingits forward movement. 7 The tension-bar has a fingerpiece 45 thereon.The guide-plate hasa finger-piece 4:6 thereon extending from the ledge41. Apivot-pin 47 is secured in a lug.

48v at the bottom of the table and passes through bearlng holes in thetension-bar and guide-plate. A spring 49 about the pivot pin bears onthe tension-bar for pressing the same toward the guide-plate and therebypressing upon the cushi0n-strip,the spring pin. V V V The guide-plateis" providedwith a .slot

being adjustable by a nut 50 on the pivot- V 54-. and the tension-bar isprovided with a hole 55 of larger diameter than the width V of the slot.A clamp-bolt 56 passes through a the hole 55 and has a shoulder 57'which bears upon thewalls of the slot 54:, the. V

clamp-bolt being threaded into a lug 58 on the lower face of the table.-i

Tliecushion-strip passes through an inclined slot 61 inthe table, acrossthe anvil,

and through an inclined slot 62 in thetable,

about-a'lug 63 atthe bottom of the table,'

and between the feed-wheel 39-and its coacting' impact-face 40, thecushion-strip extending-in the direction of feeding movement' of thematerial.

. The slots 61- and 62 are sufficiently wide to receive various widthsof cushion-strips and permit lateral adjustment of the CllSh. Vion-strips therein] If it is desired to adjust the cushion-striplaterally, theclamp-bolt- 56' is turned for releasing'the guide-plate,-which is shifted on itspivot 4:7 by means of.'

the finger-piece 46, whereby the guide-lugs 43' are shifted laterallyfor controlling the path of the cushion-strip; When the guideplate is inadjusted position, the clamp-bolt is again clamped upon the adjustableplate. The cushion-strip :is readily placed between the guide-plate andthetensiojn-bar by de-" pressing'the tension-bar by ineansof thfinger-piece 45. V

In perforating closedfmargins, for infeeding movement and so as tofollow the curves of themargin, w th the entire closed margin located atoneside of the punchstance the upper margins of closed Vamps, it hasbeen a usual practice'heretofore in machines of thischaracter to'caus'ethe margin to be guided in a path parallel with-the r ram, whichposition wouldbe to the left of the punch-ram exemplified in Fig. '1.The handling of the closed vamp while perforatingthe same, manipulated1n th1s manner,

I have found'that by providinga shift- {has been found to beextremely'difiicult and cumbersome, especially when perforatingaroundthe throat of the vamp; v

able gage I am enabled to cause a stretch ofthe closed vamp to pass thegage into punchingposition'for locating the closed margin around'thegage, that'is to say,'1nclos1ng the 'gage by the closed margimsuch arelation of parts being exemplified in Fig. 4. I have, therefore.provided a Shiftable'gageGG having a guiding face 67, against which theedge 68 of the material is arranged to'be guided during the perforatingoperation. This edge is exemplified as a folded edge.

The shiftable gage is exemplified as pivot-t ed by'means of a pivot 69to a depending bracket 70 secured to the arm of the machine. The bracketis adjustable on the arm,

asby having a clamp-bolt71 threaded into a lug 72 of the arm and passingthrougha slot 73 in the bracket, there being a tongue and grooveguide-connection 7lbetween the bracket and lug. A set-screw 7 5 isthreaded into a lug the lug 72.

A spring 78 is aranged to resiliently re- 76 of the bracket and impingestract the gage when shifted out of normal position,

the normal position being preferably Ja'gainst the material-supportingsurface. The spring is shown clamped tothe bracket by means of aclamp-screw 79 at one of its ends, the other end of the spring havingsliding movement in a slot 80 in the gage.

A hold-down finger 81 is arranged to hold down the edge of the materialbeing perforated and is exemplified as adjustable toward and from thematerial-supporting surface, so as to permit dlfferentthicknesses ofmaterial to readily pass thereunder. It.

.gage with a contact-face 85, shown inclined upwardly and rearwardlyfrom the bottom of the gage, the construction being such that when thebody of the material whose margin is to be perforated is moved past thegage toward the punch, that is, in a direction reverse to the directionin which the edge to be perforated is moved toward the guiding-face 67during the perforating operation, the outer edge 86 of the material willcontact the inclined contact-face and thereby raise the gage forpermittingthe body of the material to be shifted thereunder past thegage, so that the margin to be perforated will be brought into range ofthe reciprocating punch and under the projecting end of the hold-downfinger.

I have exemplified the relation of the parts in Figs. 5, 6 and 7 Fig. 5representing the relation of the parts as the outer edge of the materialis about to be brought into contact with the contact-face of the gage bymovement of the body of the material in the direction of the arrow a,Fig. 5 showing the relation of the parts after the body of the materialhas been brought under the gage, and Fig. 7 representing the relation ofthe parts after the edge of the material to be perforated has been movedto contact the guiding-face 67 for being guided thereby,

entire perforating operation, the

usually effected by a movement of the material in a direction reverse tothe direction indicated by the arrow a, the presser-foot and the punchduring such movements of the material being in raised positions.

Under employment of my invention, materials having closed margins, forinstance closed vamps, are readily manipulated by the operator forfeeding the clrsed margin past the gage and for having the materialadjacent to the punch, especially at the throat of the vamp, liesmoothly upon the material supporting surface, such a relation beingexemplified in Fig. 4.

In perforating the closed vamp, it is laid with its outer face upwardupon the mate rial-supporting surface, and one portion of its body, forinstance at one side of the back-seam, is presented with its outer edge86 toward the rear contact-face 85 of the gage, and slipped under andpast the gage,

which is raised thereby, its inner edge being then-presented toward theguiding-face of the gage, and the perforating begun at one 'side of theback-seam, and continued around the entire upper margin of the closedvamp to the point of beginning, substantially all portions. of the vampbeing substantially flat upon themateriaLsupport during the vamp whenperforated, being again slipped under the gage for removing the same,the gage yielding upon contact of the inner edge 68 of the vamp with therear contact-face of the gage. The operation is quickly performed andthe feeding of the closed vamp readily accomplished.

The gage and hold-down finger are represented in adjacent positions, thegage being shiftable with relation to the hold-down finger inperpendicular manner with rela tion to the material-supporting surface,for permitting the material to pass the gage while under the hold-downfinger.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent, is:
